A Nano-Mister sprays tiny water particles evenly onto the lashes to cure the glue and dry the lashes. It sounds like it would do the opposite - spraying water on the lashes sets the glue and makes them dry? But it does!
Here’s the science: most lash adhesives contain an ingredient called Cyanoacrylate, an active ingredient that must polymerize (chemical reaction that turns a liquid to a solid) for the lash glue to dry/cure. For the polymerization process to occur, hydrogen(water) must be present, which is where the Nano-Mister comes in. A Nano-Mister is used by spraying such a small amount of misted water that it activates the curing process through polymerization and allows the glue to dry/cure faster than it typically would through hydrogen in the humidity in the air.
Expert eyelash technicians suggest also using a Nano-Mister throughout the appointment to cure lash adhesive faster and to prevent any burning or stinging sensations your client may experience.
